(Number)

My vote on the proposed resolutions is as follows: (please mark the appropriate boxes):

Extraordinary General Shareholders' Meeting

1. Report of the board of directors in respect of the renewal of the powers regarding the authorized capital Communication, discussion and filing of the special report of the board of directors in accordance with article 604 of the Belgian Companies Code, wherein the board proposes to renew the powers regarding authorized capital and indicates the circumstances in which the board of directors will be able to use its powers under the authorized capital, and the purposes that it shall pursue.

2. Renewal of the powers of the board of directors under authorized capital – Amendment of the articles of association

Proposed resolution: The meeting resolves to renew the powers of the board of directors in connection with the authorized capital as follows:

(a) The board of directors will be authorized to increase the capital of the company on one or several occasions by a maximum amount of five million euro (€ 5,000,000.00).

This authorization is valid for a period of five (5) years as from the date of publication in the Annex to the Belgian Official Journal of an extract of the minutes of the extraordinary shareholders' meeting of the company held on April 26, 2017, granting the authorization, and will for the remainder have the modalities and conditions as set forth below.

(b) In light of the provisions set forth in paragraph (a), article 7 of the articles of association will be amended and reformulated as follows:

"Article 7: Authorized Capital

By virtue of a resolution of the extraordinary general shareholders' meeting held on April 26, 2017, the board of directors may increase the capital of the company on one or several occasions by a maximum amount of € 5,000,000.00.

This authorization is valid for a period of five years as from the date of publication in the Annex to the Belgian Official Journal of an extract of the minutes of the extraordinary shareholders' meeting of the company held on April 26, 2017.

These powers of the board of directors can be renewed.

The board of directors may increase the capital by contributions in cash or in kind within the limits of applicable law, by capitalization of reserves, whether available or unavailable for distribution, with or without the issuance of new shares (with or without voting rights). The board of directors may also use this authorization for the issuance of convertible bonds, warrants or bonds to which warrants or other securities are attached, and for the issuance of other securities.

In accordance with the applicable provisions of the articles of association and applicable law, when using its powers under the authorized capital, the board of directors may, in the interest of the company, limit or cancel the preferential subscription right, including in favour of one or more specific persons other than personnel of the company or of its subsidiaries.

Where, in the event of a capital increase decided by the board of directors pursuant to the authorized capital, an issue premium is paid, this issue premium will be automatically booked under the account "Issue premium", which shall, like the share capital, serve as the guarantee for third parties, and which can, except the possibility to convert this reserve into share capital, only be reduced or cancelled on the basis of a new lawful resolution of the general shareholders' meeting passed in the manner required for an amendment to the company's articles of association.

When using its powers under the authorized capital, the board of directors is authorized, with power of substitution, to amend the company's articles of association to reflect the outstanding share capital and outstanding shares."
